ST Engineering has signed a multi-year engine maintenance, repair and overhaul (MRO) agreement with Xiamen Airlines to support the airline’s CFM LEAP-1A engines through their first Performance Restoration Shop Visit (PRSV). The agreement was announced on February 4 by ST Engineering’s Commercial Aerospace business.
The deal represents a significant expansion of the long-standing partnership between the two companies, as Xiamen Airlines continues its fleet modernisation with new-generation aircraft powered by LEAP engines.
Building on a 35-Year Relationship
